Background technology
As the non-renewable resources such as current coal, oil and natural gas increasingly depleted develops, renewable resource becomes
Inexorable trend.Cellulose is natural polymers most abundant in nature, has biodegradability and recyclability.
Fully excavate cellulose Potential performance exploitation using cellulose as raw material novel product by be sustainable development important topic
One of, cellulose particularly microcrystalline cellulose and nano-cellulose are applied as a kind of new packing in macromolecule matrix, energy
Enough assign the performances such as light composite material, high intensity, high-modulus, high water absorption biology, degradability.
The chemical constitution of cellulose is each other with β-Isosorbide-5-Nitrae-glycosidic bond with C by D- glucopyras saccharide ring- 1Chair conformation joins
Tie the linear macromolecule that forms, cellulose is widely present in plant fiber that wherein the content of cellulose of cotton close to 100%, is
Most pure natural fiber usually source.Cellulose accounts for 40%, 50% hemicellulose and 20%, 30% for also having 10%, 30% in general timber
Lignin, numb straw, straw, bagasse etc. are all the abundant sources of cellulose in addition.
White carbon is one of main reinforcing agent of rubber, but white carbon black production is high energy consumption process, and white carbon exists
It is more difficult scattered in rubber mass.
Cellulose surface contains the active group with white carbon similar quality, if cellulose can replace white carbon to be used for rubber
The enhancing of glue will be with important social effect.
